SCHULTZ SYPHON DISPE NSING-SIPHON.

Application filed December 6, 1906.

To all whom it may concern:

Be it known that I, JOHN A. SoHUL'rz, Jr., a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Dispensing-Siphons, of which the following is a specification.

' This invention relates to that class of receptacles or containers which are usually made of glass and used for distributing and dispensing small quantities of fermented and carbonated beverages under pressure, whereby the liquid can be had as fresh and palatable as if drawn directly from the keg.

The objects of the present improvements are to simplify the construction of such a device, or siphon, as it is generally termed; to secure a substantially straight flow passage for the liquid, so that it will not be caused to foam unduly; to combine the discharge spout with the controlling valve and avoid a multiplicity of projections from the sides of the gas dome; to prevent the discharge spout from rotating; to provide improved means for controlling and operating the valve, and to obtain other advantages and results may be brought out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 is a side elevation of the upper portion of a dispensing siphon of my improved construction, looking toward the discharge spout, and Fig. 2 is a similar view taken from a point at right angles to the view point in Fig. l, or looking sidewise at the discharge spout; Fig. 3 shows the siphon head with its walls partly broken away to disclose the interior more fully, and Fig. 4 is a sectional view taken on line a, Fig. 3, and looking in the direction indicated by the arrow; Fig. 5 is a view of the controlling valve seat formed in the outer wall or side of the gas dome; Fig. 6 isa View showing the valve in closed position, the outer discharge spout having been moved, and Fig. 7 is a similar view showing the valve in open position; Fig. 8 shows a wrench for turning the dis charge spout or its retaining cap into position to hold the valve in place; Fig. 9 is an outer end view, and Fig. 10 a side View, of a certain bushing by which the inner end of the discharge spout is held; Fig. 11 shows in end and side View, a key for operating the Specification of Letters Patent.

controlling valve of my dispensing siphon; Fi 12 is a front View of the controlling va ve detached; Fig. 13 is an edge view of the same; Fig. 14 is a rear or inner face view of the valve, and Fig. 15 is a section taken upon line 0 Fig. 14.

In said drawings, 1 indicates the liquid reservoir of my im roved siphon, which is the usual glass bott e or receptacle adapted to have the gas dome or siphon head 2 secured to its to or neck, as is common in the art. Said sip on head is of substantially cylindrical shape with a rounded top and an annular lower portion 3 at its outer edge, which depends around the neck of the bottle or reservoir 1, so as to lie at its lower edges close against said reservoir. This siphon head 2 it will be understood, is hollow and rovides a chamber to be charged with gas to 'urnish pressure for emptying the liquid reservoir. A s out 4 projects from one side of the siphon ead, and at the base of said spout is a valve in connection therewith for controlling the flow of liquid from the reservoir through said spout, and the passage of air from the gas dome into the liquid reservoir. This is the only point at which the outer surface of the siphon head has a projection or protuberance of any sort. In the construction of said outlet and controlling valve, an annular flange or projection 5 is formed on the outer side wall of the gas dome and preferably integral therewith; said flange or projection 5 receives or incloses the valve pro er 6, and the floor of its chamber forms wit 1 the contacting face of said valve, an impervious joint. The outer edges of the annular flange 5 are exteriorly threaded to re ceive a cap 7 which screws thereon and serves to hold the discharge spout 4. This discharge s out comprises simply a piece of suitably lient tubing having secured thereto at its base an outer ring 8 to be engaged by the said cap 7, and also to form an im ervious being made more positive by an annular proj ection 9 upon the end face of the said ring 8, and which presses into the valve 6. The outer edges of the ring 8 have lugs 10 to enter slots 11 in the edge of the flange 5, and thushold the discharge spout 4 from turning when the cap 7 is tightened up into final position by means of the spanner wrench 12, being applied to its outer periphery, which has the apertures 13 to receive it. F urthercontact with the valve proper 6, sai contact more the said cap 7 may be provided with a peripheral projection 14 having a series of apertures 15, some one of which when the cap is turned into final position registers with a tapped hole in a bottom lug 16 on the siphon head, so that a screw 17 may be inserted. Obviously other means for locking the cap in its position could beemployed if desired.

The valve proper 6 has an oblique trans verse passage 18, which opens through the center of the valve at its outer side so as to always register with the passage of the discharge spout 4; the other end of the passage 18, however, opens on the inner face of the valve at a point out from its center, and is thus adapted as the valve is turned to pass into, or out of, registration with the end of a duct 19, which leads through the chamber of the gas dome and bending downward is adapted to extend through the bottom of the gas dome and into the liquid reservoir to a point at or near the bottom of the said reservo1r.

For controlling the passage of gas from the dome into the liquid receptacle, the floor of the seat for the valve 6 has two apertures 20, 21, one of which, as 20, opens into the dome chamber, while the other 21, communicates with the tube 22, which extends through the chamber and bends downward through the bottom of the gas dome to enter the top of the liquid receptacle. The valve 6 is then provided at its inner face with openings 23, 24 connected by a passage 25 through the body of the valve, said openings being so dis posed that when the flow port 18 is in open position, as above described, they will register with the gas apertures 20, 21 in the valve seat and so admit gas from the dome to the liquid receptacle. When the valve 6 is turned, however, to carry the inner end of the flow duct 18 out of registration with the passage 19, as shown in Fig. 6, the openings 23, 2 1 are carried out of registration with the'apertures 20, 21, and the passage of gas cut 011. For turning the said valve 6, the flange 5 is for a side portion of itself recessed or slotted, as at 26, and the peripheral edge 01' the valve is provided with a socket 27 to receive a key 28, which can then be operated as a lever to turn the valve. Preferably the said socket and end of the lever are given an odd shape, as shown in the drawings, in order to prevent tampering with other than the proper keys. Furthermore, in order to prevent any burs formed by the use of the key, obstructing the removal and replacing of the valve proper 6 in its seat, I prefer to provide the inner wall of the flange 5, for the length of the slot 26, and outside the same, with the segmental recess 29. Alug 30, on the periphery of the valve proper then projects into this segmental recess 29, which recess is made sufliciently longer than the slot 26 at its lower end so that when the lug 30 lies at said lower end the key socket 27 will be in radial alinement with the end wall of the slot 26 to receive the key 28. Obviously as the said key is thrown upward its engagement with the top end of the slot 26 limits movement at exactly that point where all the ports are in registration, as shown in Fig. 7. When again thrown down, flow is cut oil as in Fig. 6 and the key is taken out and carried away. Obviously the key 28 instead of being made separable as described so as to prevent tampering with the device, could be attached or inserted permanently in the valve 6 and serve merely as a lever which would always be in position for use.

To prevent prolonged dripping from the spout 4, after the valve is closed, a vent 31 is formed in the top of said spout, as shown in the drawings. Preferably this vent terminates at its outer end within the cap 7, and thus serves not only as a vent for the spout, but also as a relief opening should any one attempt by placing his finger over the end of the spout and opening the valve, to supercharge the liquid receptacle or overcarbonate the liquid therein. In such an event obviously beer would escape through the vent 31, cap 7 and its peripheral apertures 13, so that the pressure would be relieved, and it would be practically impossible for the mischievous person to close said apertures to prevent it.

Having thus described my invention, what I claim as new is;
